Turnkey Water Treatment System


With the help of our farmers, Pursanova designed an industrial grade system specifically for the farming industry. Our driving force and mentor on this project were renowned farmer Keith Schlapkohl. When we spoke to Keith, he suggested that “We need an RO System that is specific to farming and not one that is made for everyone.” After months of testing and development—that’s exactly what we created. Using Keith’s extensive field experience, we developed a system that is focused on the daily use and needs of a farmer.

Before we began manufacturing, there were many variables to address such as rust issues, downtime, quality, and performance. Keith encouraged us to expand our research by seeking feedback from other farmers such as Jerry & Erik Carlson, the Hostetler family, Jeff Littrell, Jeff Buresh, the Knoblock family and Jon Blomgen of JRT Focus Farms, and Agronomists Bob Streit, Michael McNeill and Amie Bandy (to name a few). Below is a sample for a 4,400 Gallon per Day (GPD) system that we created:

Reverse Osmosis System - 4,400 GPD

System production is based on the following conditions:

2,000 ppm Nacl Feed water, 77 °F / 25 °C Operating temperature and 3.0-11.0pH range. Actual feed water analysis may require special design consideration affecting final design and pricing.
